I can give you a tough idea of it. I'm currently running a log and it works well. My strength ha deff Gone up too. My buddy took it an his strength went up and he thinks it's all mental. It's hard to explain because it's not something you really notice but you think it's working

I used it for a month. I can give a rough idea but I'm not so tough. It is a pretty good product. It seems to take some time to really kick in. I got a second bottle but it didn't arrive on time for me to continue my cycle. Really think it should be run at least 8 weeks as I really started noticing the effects at the 3 week mark. Increases in strength and endurance but they it wasn't immediate. It more or less creeps up on you and the gains a slow and steady.
